These speakers are small (pocket sized) but certinaly don't lack in quality. The bluetooth connectivity means you can wirelessly stream your music to the speaker from your bluetooth enabled device. Although, you can still use the aux input if you want a wired connection.
The handsfree function is a great addition. Simply press the call button on the top of the speaker to answer any calls you have. The music will cease playing whilst your in conversation. Press the button again and your music will automatically resume.
How does it charge?
The PocketBoom has a mini usb input so you can use a mini usb cable (cable) to plug it in to a USB mains chargers. Please do not confuse a mini usb with a micro usb cable.
